Safariland 6390RDSO ALS® Mid-Ride Level I Duty Holster – Glock 17/19/45 Gen 4-6

The Safariland 6390RDSO is an optic-ready, Duty Rated Level I retention holster for compatible pistols fitted with a red dot sight. The ALS® Automatic Locking System secures the pistol when holstered and releases with a natural thumb motion for a straight-up draw.

Its RDSO design leaves an open pocket around the optic instead of using a flip-up dust cover. The included mid-ride belt loop positions the holster at a practical duty-carry height close to the body.

The rigid SafariLaminate™ shell is thermoformed for a consistent fit, and the suede-lined interior helps protect the pistol's finish and sights. Choose the holster configuration for your exact pistol and weapon light. Optic model, mounting position and aftermarket modifications can affect fit.

• Open RDSO optic pocket without a flip-up dust cover.
• The light and optic lists above apply to the corresponding holster version, not to every 6390RDSO configuration.
• Optic fit also depends on the mounting plate, mounting height and position on the slide. Safariland does not guarantee compatibility with every aftermarket optic installation.

CARRY AND MOUNTING
• Mid-ride belt loop included; positions the holster close to the body.
• Glock 19/45 packaging specifies a CUBL2 mid-ride belt loop, model 6070CUBL2, for a 2.25-inch (58 mm) belt.
• Standard Safariland three-hole mounting pattern.
• QLS 19 Locking Fork and QLS 22 Receiver Plate are not included. A compatible QLS kit is available separately.

FIT CHECK
Check correct seating, ALS locking and unobstructed release with your exact pistol, optic and light combination. Threaded barrels, compensators and other aftermarket modifications require a separate compatibility check.
